|
|
common cause of Respiratory acidosis
|
*abnormalities in pulmonary ventilation leading to CO2 retention.
*Halted or hindered gas exchange *Obstructions preventing exhalation of CO2 *Impaired neuromuscular function or integerity of chest wall *Depressed Respiratory center in medullat |
|
|
Etiology of Respiratory acidosis
|
ARDS, Pneumonia, Atelectasis, COPD, emphysema, asthma, bronchial burns, chest trauma, Guillain-Barre, MS, Mysathenia gravi, Drug overdoses, anesthesia, acute alcoholism.
|
|
|
Compensatory mechanisms that take place within 24 hours of Respiratory Acidosis
|
Kidneys conserve HCO3 and excrete more hydrogen ions into urine
Urine becomes more acidotic |
|
|
Clinical manifestations or signs of respiratory acidosis
|
Drowsiness, unconsciousness, disorientation, rapid, shallow respirations, tachycardia, dizziness, decreased BP, headache, Tachycardia, seizures
|
|
|
How can we improve respiratory function?
|
antibiotics for infection, postural drainage, bronchodilators, inhalation therapy, breathing exercises, mechanical ventilation, oxygen therapy.
|
|
|
What is the 2nd intervention in correcting respiratory acidosis? and how do we correct that?
|
Correct Acidosis
through treating hyperkalemia if present and IV sodium bicarbonate |
